In New York, a passenger train on the Hudson River Line derails and injuries are reported, one fatal
A seven-car Hudson River Railroad passenger train on its upriver journey derailed in mid-afternoon near Sing Sing, New York after a switching error. The locomotive and two other cars were thrown into the Hudson River. Speed had been reduced and the rear five carriages remained on the tracks after the engineer's attempts to slow further. Still, one passenger was killed and several more badly injured. (By John Osborne)
